Detective Butler: Maiden Voyage Murder

Detective Butler: Maiden Voyage Murder is a free-to-play visual novel that originally released on May 26, 2017 and has since received two pieces of DLC: a Soundtrack (released on launch day) and a Choices DLC (released April 27, 2020) that added branching paths, alternate routes, and new endings to the game. Both DLC items are fully released with no unreleased content listed on the store. Following the Choices DLC launch in April 2020, the developer noted they might add more choices in future updates but immediately clarified that their focus would shift to the sequel, Detective Butler and the King of Hearts. In December 2020, the developer shipped a significant engine upgrade enabling Mac and Linux support, which represented the last meaningful content/technical update to Maiden Voyage Murder itself. Subsequent news posts (February and March 2023, August 2023) are entirely focused on the sequel's development progress — announcing its Steam page, a demo, and community-building efforts around mystery games. None of these posts announce or hint at any new content coming to Maiden Voyage Murder. The last developer communication of any kind touching on this game was August 10, 2023, and it was a retrospective anniversary post. With both DLC released, no unreleased content listed, no developer statements about future content for this title, and developer focus clearly shifted to the sequel since at least 2020, the game is effectively complete. The December 2020 engine upgrade is the most reasonable endpoint for the game's content development, as it rounded out platform support and finalized the package.
